NVIDIA Jetson T4000 vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for the NVIDIA Jetson T4000 versus the NVIDIA N1X 40SM. Both entries report an average benchmark score of zero and a percentile ranking of 50 against all GPUs. This absence of empirical data means any comparison must rely entirely on the architectural specifications recorded for each part.

The raw compute figures, however, tell a stark story. The N1X 40SM delivers 24.02 TFLOPS of FP32 throughput, which is approximately 5.1 times the 4.700 TFLOPS recorded for the Jetson T4000. The FP16 figures mirror this exactly, with both parts showing a 1:1 ratio between FP16 and FP32, so the N1X 40SM maintains the same 5.1x advantage in half-precision workloads. The shading unit count confirms this disparity: the N1X 40SM packs 5120 shading units against 1536 on the Jetson T4000.

The N1X 40SM also dominates in texture and pixel processing. Its texture rate reaches 750.7 GTexel/s, compared to 73.44 GTexel/s on the Jetson T4000, a difference of roughly 10.2 times. The pixel rate gap is similarly wide: 93.84 GPixel/s versus 24.48 GPixel/s, a 3.8x margin. These figures indicate that the N1X 40SM is not merely faster, it is in a different performance class altogether.

Clock behavior presents a more nuanced picture. The Jetson T4000 runs at a fixed 1530 MHz for both base and boost, suggesting a locked, power-constrained design. The N1X 40SM has a base clock of 741 MHz but boosts to 2346 MHz. The boost clock on the N1X 40SM is 816 MHz higher than the constant clock on the Jetson T4000, a 53% uplift. The low base clock on the N1X 40SM likely reflects power management at idle or light loads, while the high boost clock enables the substantial compute advantage when fully engaged.

Memory capacity favors the N1X 40SM decisively. It offers 128 GB of LPDDR5X memory, double the 64 GB found on the Jetson T4000. Both parts use a 256-bit bus and the same memory clock of 1067 MHz with 8.5 Gbps effective, producing identical bandwidth of 273.2 GB/s. The bandwidth parity means that memory-bound workloads will scale with capacity rather than throughput, and the N1X 40SM can hold twice the dataset in local memory.

Ray tracing and tensor hardware follow the same pattern. The N1X 40SM includes 40 RT cores and 160 tensor cores, versus 12 RT cores and 64 tensor cores on the Jetson T4000. These are 3.3x and 2.5x advantages respectively. For AI inference and ray-traced rendering tasks, the N1X 40SM has substantially more dedicated hardware available.

The physical specifications reinforce the positioning. The Jetson T4000 measures 87 mm by 100 mm by 15 mm, while the N1X 40SM has no recorded dimensions. Both are integrated graphics processors (IGP) with no power connectors, and both use the PCIe 5.0 interface, though the N1X 40SM utilizes x16 lanes versus x8 on the Jetson T4000. The Jetson T4000 carries a 90 W TDP and a suggested PSU of 250 W, while the N1X 40SM has no power figures recorded.

The Verdict

The data points to two very different products despite the shared NVIDIA lineage and 5 nm TSMC process node. The N1X 40SM is the clear performance leader by every measurable compute metric. Its 24.02 TFLOPS FP32 throughput, 750.7 GTexel/s texture rate, and 93.84 GPixel/s pixel rate place it far above the Jetson T4000's 4.700 TFLOPS, 73.44 GTexel/s, and 24.48 GPixel/s. The 5120 shading units versus 1536, 40 RT cores versus 12, and 160 tensor cores versus 64 all reinforce this hierarchy.

The memory configuration adds another layer. The N1X 40SM's 128 GB capacity doubles the Jetson T4000's 64 GB, while bandwidth remains constant at 273.2 GB/s. This makes the N1X 40SM suitable for larger models and datasets that would exceed the Jetson T4000's memory footprint.

The Jetson T4000 does hold advantages in specific areas. Its 1530 MHz constant clock is higher than the N1X 40SM's 741 MHz base clock, which may translate to more predictable performance in latency-sensitive or sustained workloads that do not trigger boost behavior. The Jetson T4000 also has a recorded 90 W TDP and a 250 W suggested PSU, whereas the N1X 40SM has no power data, leaving its requirements unspecified.

The release timing separates the two as well. The Jetson T4000 launched on January 4, 2026, while the N1X 40SM arrived on May 31, 2026, roughly five months later. The Jetson T4000 has a launch MSRP of 1,999 USD; the N1X 40SM has no recorded launch price.

For buyers, the choice depends on workload scale. The N1X 40SM is the choice for maximum compute throughput, larger memory footprints, and higher-bandwidth PCIe connectivity. The Jetson T4000 suits scenarios where a fixed clock, lower power envelope, and compact physical footprint (87 mm by 100 mm by 15 mm) are priorities, and where the workload fits within 64 GB of memory.

Architecture Differences

Both chips are fabricated on a 5 nm process at TSMC, but they represent different architecture revisions. The Jetson T4000 uses the GB10B chip with Blackwell architecture, while the N1X 40SM uses the GB20B chip with Blackwell 2.0. The generation labels confirm this split: Server Blackwell (Bxx) for the Jetson T4000 and Blackwell IGP (N1x) for the N1X 40SM.

The shading unit count difference, 1536 versus 5120, indicates a fundamentally different streaming multiprocessor configuration. The N1X 40SM has 40 SMs as its name suggests, while the Jetson T4000's smaller count reflects a more constrained design. The TMU and ROP counts scale accordingly, with the N1X 40SM at 320 TMUs and 40 ROPs versus 48 TMUs and 16 ROPs on the Jetson T4000.

Ray tracing and tensor hardware also differ substantially. The N1X 40SM includes 40 RT cores and 160 tensor cores, compared to 12 RT cores and 64 tensor cores on the Jetson T4000. The N1X 40SM's 40 RT cores match its SM count, suggesting one RT core per SM. The Jetson T4000's 12 RT cores against 1536 shading units implies a 128-shading-unit-per-RT-core ratio, a sparser allocation.

The FP16 to FP32 ratio is 1:1 on both parts, indicating no dedicated half-precision path difference in the recorded specifications. Both reach 4.700 TFLOPS and 24.02 TFLOPS respectively for both precision formats.

The memory architecture is identical in type, bus width, and bandwidth. Both use LPDDR5X over a 256-bit bus at 273.2 GB/s. The capacity difference, 64 GB versus 128 GB, likely stems from different memory module configurations or board designs rather than a different memory controller.

The PCIe interface differs, with the Jetson T4000 using x8 lanes and the N1X 40SM using x16 lanes. Both are PCIe 5.0. Display output also differs: the Jetson T4000 has no outputs, while the N1X 40SM has one HDMI port.

The Jetson T4000's 90 W TDP with a 250 W suggested PSU provides a power envelope, while the N1X 40SM has no power data recorded. The Jetson T4000's dimensions of 87 mm by 100 mm by 15 mm are recorded, but the N1X 40SM has no physical size data.

Where Each One Wins

The N1X 40SM wins decisively in raw compute throughput. Its 24.02 TFLOPS FP32 and FP16 performance dwarfs the Jetson T4000's 4.700 TFLOPS. For large-scale parallel computation, neural network training, and batch inference, the N1X 40SM has a clear advantage.

The N1X 40SM also wins in graphics-centric workloads. Its 750.7 GTexel/s texture rate and 93.84 GPixel/s pixel rate are 10.2x and 3.8x higher respectively than the Jetson T4000's figures. The 40 RT cores against 12 make the N1X 40SM substantially better suited for ray-traced rendering.

Memory capacity is another N1X 40SM win. The 128 GB footprint supports larger models and datasets than the 64 GB on the Jetson T4000. For workloads that require holding extensive data in local memory, the N1X 40SM avoids spills to system memory or storage.

The PCIe 5.0 x16 interface on the N1X 40SM provides double the lane width of the Jetson T4000's x8 connection. This favors the N1X 40SM for data transfer between the GPU and host system.

The Jetson T4000 wins in specific operational characteristics. Its fixed 1530 MHz clock provides consistent performance without boost variability. The N1X 40SM's 741 MHz base clock is much lower, so sustained workloads that prevent boosting may run slower on the N1X 40SM.

The Jetson T4000 also wins on power predictability. Its 90 W TDP and 250 W suggested PSU give a clear power requirement, while the N1X 40SM has neither figure recorded. Systems with strict power budgets may prefer the documented envelope of the Jetson T4000.

Physical size favors the Jetson T4000, with recorded dimensions of 87 mm by 100 mm by 15 mm. The N1X 40SM has no dimensions recorded, so the Jetson T4000 is the only one with a confirmed compact footprint.

The Jetson T4000 has a launch MSRP of 1,999 USD, while the N1X 40SM has no recorded price. The Jetson T4000 also launched earlier, on January 4, 2026, versus May 31, 2026 for the N1X 40SM. Both are marked as Active in production status.

The data indicates that the N1X 40SM is the performance-oriented choice, while the Jetson T4000 is the predictable, power-bounded option with a confirmed form factor. The 5.1x compute gap and 2x memory gap place these in different tiers despite their shared manufacturer and process node.
